Mac mail setup problems

We have a huge problems setting up our email accounts of the cPanel within the Mac Mail applications. We can get incoming mails but can't send any mails. We tried the automatic setup scripts and both normal and ssl connections.
Can you please help us out with this,

Are you specifying port 25 to send mail? Many internet service providers block port 25 for their customers, as a means of trying to control spam. Your host may have configured the server to listen on an additional port in order to help its customers void this problem, but only your host will know if this configuration is set. You will need to talk to your host for help with this.
